To @ZZ whom, it may concern:

Be it known that I,DAv1D LONIE, a subject of the King of Great Britain,and a resident of Fairview, in the Province of British Columbia andDominion of Canada, have invented a new and Improved Pulp-Distributer,of which the following is a full, clear, and exact description.

My invention relates to pulp-distributers intended for general use, andmore particularly to such types of pulp-distributers as are used inconnection with cyanid-mills and similar apparatus for extractingprecious metals from ores and tailings.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorrespondingl parts in all the igures.

Figure 1 is a side elevation, partly broken away, showing the mechanismready for use. Fig. 2 is an enlarged section upon the line 2 2 of Fig. 1looking in the direction of the arrow and showing the automaticdumpingpan. Fig. 3 is a diagrammatic plan view showing theradially-movable chute. Fig. 4 is an enlarged fragmentary sectionthrough the radially-movable chute, showing the gates 30, 31, and 32,together with means for adjusting the same g and Fig. 5 is a perspectiveview of the joint used for allowing the chute to be raised for purposesof moving the same from one tank to another.

An elevated track 6 is engaged by a car 7, provided with wheels 8, eachdirectly engaging the track. Depending from the car 7 is a stem 9,provided with a head 10. Depending from this head 10 is another stem 11,provided with a head 12, the heads 10 and 12 being connected by a pivot13. By this means the stem 11 is adapted to swing relatively to the stem9, as will be understood from Fig. 5. A key 14 is inserted through holes15 16 in the heads 10 and 12 and normally prevents the stem 11 fromswinging. (See full and dotted lines in Fig. 5.) Encirclingthe stem 11is a tube 17, which is mounted upon the bottom 18 of a chute 19, thelatter being adapted to move angularly around the stem 11 as a center.An angle-block 20 engages the under side of the chute and is supportedby an annular plate 21, the latter being held in position by means of apin 22, so that it may be readily disengaged by withdrawing the pin.Mounted upon the top and bottom oi' the chute 19 are beams 23 24, heldagainst the chute by bolts 25, secured rigidly in osition by means ofnuts 26, as will be midierstood from Fig. 2. The chute 19 is providedthroughout its entire length with a series of dams 27 28 29, and overthese dams is a series of gates 30, 31, and 32, the latter beingprovided with pins 33, which are each engaged by a thumb-nut 34, as willbe understood from Fig. 4. Beneath each thumbnut is an annular plate 35,which engages a bridge 36, provided with a slot 37. v By loosening thethumb-nut 34, moving the gate 30 to the desired angular position, andtightening the thumb-nut the several gates ma be adjusted to dilferentangles. (See Figs. 3 and 4.) Each gate, such as 30, 31, and 32, is alsoconnected with a hinge 32L to accommodate its position to any angledesired. Surmounting the outer end of the chute 19, so as to support thesame, is a bearing 38, connected by bolts 39 with an eye 40. Connectedwith this bolt is a tie-rod 41, provided with a turnbuckle 42. Engagingthis tie-rod is a brace 43, which engages the lower side of the chute,as will be understood from Fig. 1. The tie-rod also engages an eye 44,disposed comparatively near the opposite end of the chute. A revolubleshaft 45 is provided with set-collars 46 47 and is free to turn. Moimtedrigidly upon this shaft 45 is a wheel 48, provided with a iiange 48u andengaging the upper surface 49 of a cylindrical tank 50. Then the chute19 is moved angularly around the stem 11 as a center, the wheel 49simply rolls aroimd upon the top of the tank, as will be understood fromFig. 1.

A hook 51 is connected with and depends from a carriage 52, adapted totravel along the track 6. This hook 51 supports the shaft 45 and thechute 19 when the latter are raised into such position that the hook maydirectly engage the shaft. When the shaft and the chute are thus raisedand supported, the entire chute, together with all of its immediateattachments, may be moved around the track 6 from one tank to another.By means of hinges 51 a dumping-pan 52 is supported in such positionthat it may readily be lled, as will be understood from Fig. 2. Mountedupon opposite sides of the dumping-pan 52 are pins 53, which passthrough slots 52 in a fork 55, the latter being readily mounted IOS uponand movable with a rocking beam 54.` A weight 56 is slidably mountedupon this rocking bolt 57, whereby it may be adjusted relatively to the`rocking beam. This thumbbolt is adapted to engage different holes 58,

so that by moving the weight 56 to any de,-n

vmixed with water, the weight of the pan is so increased that thecounterweight 56 is raised slightly and the pawl 61 and the ratchetwheelcause the shaft 45 to turn to a small extent. This causes a partialrotation ofthe wheel 48, and therefore advances the general position ofthe chute 19. The idea is that the chute 19 moves around step by step,each step representing a filling and emptying of the dumping-pan. A box62 is provided with an opening 63 and with a handle 64, the latter beingused for lifting it from and replacing it upon the car 7. The trough 65is cut away at 66, so as to allow the box 62 to be placed within it, asindicated in Fig. 1. When the box is in the position shown, the opening63 registers with the trough 65, so that the tailings may pass obliquelydown through the trough 65, opening 63, and box 62. Encircling the tube17 is a hopper 67, provided with an aperture 68, opening into the chute19.

The operation of my device is as follows: The car 7, provided with thebox 62, is moved along the track 6 to a point directly over the tank 50,of which there may be any number disposed at intervals below the track.The car 7 is now centered relatively to the tank, and the hook 51 isreleased, so as to lower the wheel 48 into engagement with the uppersurface 49 of the tank. The tailings are now discharged through thetrough 65, passing downward into the hopper 67 and thence into the chute19. The several gates 30, 31, and 32 having been adjusted to differentangles, as indicated .diagrammatically in Fig. 3, the tailings aredischarged over the several dams 27, 28, and 29, substantially the sameamount passing over each dam. In this way the distribution as madeabsolutely equal, the same quantity being discharged from a dam near thecenter as from a dam near the outer circumference of the tank. The panl52 is now filled, and owing to the superincumbent weight of thematerial contained it dumps into the tank automatically, as abovedescribed. Each motion of the dumping-pan 52 turns the shaft 45 andcauses the chute 19 to move one step forward, as above explained.

beam and is provided with a thumbis opened a little wider for the inowof the tailings, and this insures evenness of distribution. When it isdesired to move the chute 19 and its accompanying parts to another tank,the shaft 45 is lifted, so as to be supported by the hook 51, and thecar 7 is pushed along the track. The box 62 may be lifted out for thepurpose of adjusting it to the next inlet-chute 65.

By the arrangement above describedl a single chute and its accompanyingparts can do the entire d istributmg-work of a cyanid plant containing aconsiderable number of tanks.
